A high precision reverse engineering design method for complex structural component which based on the meta feature is presented. The defining method for minimal discretization meta feature is studied through the case study of an axial compressor’s impeller. Then the evaluation model of matching quality between RE planning and meta features on the basis of feature analysis and fuzzy synthesis evaluation method is put forward to select the optimal RE planning for different kinds of meta features. Combined with the split silicone mould replication method in engineering, the 3D geometry data acquisition is accurately accomplished and the reconstruction of the impeller’s model is realized from the geometric constraint angle of view and the point cloud registration of multiple views technology based on characteristic constraint. The results indicate that this method is effective for improving the measuring efficiency and quality.
